A student performed three CH₂Cl2 layer titrations in Part 2 using a standard sodium thiosulfate solution with a concentration of 0.01153 M. They reported the following measurements: Final CH₂Cl2 Layer Burette Reading Initial CH₂Cl2 Layer Burette Reading Final Thiosulfate Burette Reading Initial Thiosulfate Burette Reading Determination #1 Determination #2 Determination #3 25.68 mL 17.59 mL 27.87 mL 0.24 mL 32.27 mL 25.68 mL 23.88 mL 0.41 mL 40.05 mL 32.27 mL 26.78 mL 0.22 mL How many moles of iodine did they use in their second titration (ie. their second determination)? Report your answer to the correct number of significant figures and only report the numerical value (no units).
